If I remember right, it was vehicles made after 2003/2004? If I get some spare time, I will give them a shout and get the scoop.

The Trans-go kits come in two varieties, the light version which can all be accessed through the oil pan. That version is the cheaper one and upgrades the accumulator plate along with a few solenoid springs and goodies. The bigger kit is usually around the $100 mark and comes with improved spring clips. This kit you have to pull the transmission to get everything on.

All new parts went into the transmission including a shift solenoid body. The kit really made a good difference. It don't really think it should be classified as a shift kit, more like a "fix what Mopar didn't" kit. It holds onto 1st gear a little longer at WOT. No waiting for the gear to engage when shifting from park. Up shifts are smooth and seamless as well as down shifts. You really have to pay attention to feel the shifts because it is so smooth now. Best way to describe it is, Solid. Running better than the day it came off the production line.

At this point, I highly recommend this kit, especially if you have the transmission out of the vehicle. If not, put in the shift kit accessible through the pan and save the rest for when the trans has to be rebuilt.

One thing to note, the transmission filter only had 9,000 miles on it and it had already split. Not sure if that had anything to do with the day I broke it, or if that was part of why it broke, but the filter failed....and rather early at that. So keep an eye on that fellow WK Jeepers.

Got home today from a 5 month deployment and fired up the Jeep. Running good, took a minute to run out the flat spots in the tires. Trans is impeccable. I was however given the gift (by the Jeep) of 4 new DTC's.

So needless to say, there is going to be some work going down. Just hope it doesn't strand me being I got quite a few miles to log over the holidays. I do plan to get my Aspen Creek recovery shackles on here in the next few days.

I do have a super chips but haven't use it for calibration, and I don't have the trans tuner app. I run the performance 87 tune majority of the time. Performance is good, considering it's the 4.7 and my mixed driving has been yielding mid 14's (EVIC) mpg since I got home. Best I have seen on the highway is 19. Haven't tried at stock settings yet.
